Number Facts
I don't know what 5 + 8 is, so I think about what I do know.
I know that 5 + 5 = 10, and I know that 8 = 5 + 3
So I'll take 5 + 5 = 10, and then add the 3 left over
10 + 3 = 13.

Ten Frame Facts
8 + 5 = ?
8 on one ten frame, 5 on another (we drew them). When we put them together we can take two from the 5 frame which gives us an even 10, with 3 left over, making 13 total.
